TL;DR

Customer lifetime value estimates the net profit expected from a customer over the relationship using retention and margin, not just one month of revenue.

Definition

Customer lifetime value (LTV) is the present value of the gross margin a customer generates over their expected lifetime. It is calculated from cohort retention, purchase frequency, and margin rather than a single-period average. LTV links product experience to financial sustainability and clarifies which segments deserve investment.

Decision impact

• Sets the ceiling for acquisition spend and payback assumptions by segment or channel.
• Determines which retention or upsell initiatives deliver the highest long-term return.
• Guides pricing or contract-length changes when lifetime value is below target.

Key takeaways

• LTV should be margin-adjusted; revenue alone overstates value.
• Cohort retention curves are more reliable than single-period averages.
• LTV varies by channel, plan, and onboarding quality, so treat it as segmented.
• Improving retention often lifts LTV more than raising price.
• Use LTV with CAC to test whether growth is economically sustainable.

Misconceptions

• LTV is fixed; it shifts as churn, pricing, and product value change.
• A high average LTV means all customers are profitable; segments differ widely.
• Forecasts without retention data are enough; churn is the core driver.

Worked example

A B2B SaaS tracks cohorts and sees small firms churn after six months while mid-market customers stay for two years. With 70% gross margin, the mid-market LTV is several times higher. The team shifts onboarding resources to mid-market accounts, introduces annual plans, and reduces paid spend in the small-business channel. LTV rises and growth becomes cash-flow positive.
